If Flint water is unsafe, what about yours?

January 27, 2016 – By Jasmine Watts in Great lakes Echo. Editor’s Note: Evansville has had its own lead problem and although not as ubiquitous and pervasive as the problem in Flint, it was every bit as much of a threat to human development for those who were forced to live in lead tainted neighborhoods. Sadly, that problem, once discovered, took more than twenty years to correct due to the lack of official leadership concern in Evansville as well as bureaucrat morass and delay. How many of us actually know if we have lead solder or lead piping for our service lines? The use of faucet filters is always a wise investment.Water

While Flint struggles with lead in its water, other aging Michigan communities also have water lines made of the health-threatening metal.

The National Drinking Water Advisory Council said in 2014 that there is no safe level of lead. It’s a costly problem to address.

An American Water Works Association report, “Buried No Longer,” said the nation needs to replace aging pipelines that may contain lead or may leak. Over a 25-year span, “Buried No Longer” estimates that the country’s new drinking infrastructure will cost $1 trillion.

According to the report, the total replacement cost of water pipes in the Midwest would be about $486 billion. Public Sector Consultants is analyzing Michigan’s infrastructure to find costs and needs related to fixing or replacing wastewater and drinking water systems. The Lansing-based research and program management firm specializes in governance and regulation, health care, education, energy and environmental policy.

“Although the report is still being drafted and we can’t release the results, part of our analysis is looking at the flaws in the EPA survey about drinking water,” said Jon Beard, a consultant at Public Sector Consultants.

Beard says that there have been far too many underreported cases of decrepit pipelines that lead to underestimating the problem. The assessment of need in the EPA survey is for 20 years from the time of the survey, which also causes discrepancies.

Homes with plumbing systems built before 1978 have copper and cast iron pipe connections. The American Water Works Association report says that these pipes can contain lead.

“If there is lead within one source in the home, there is probably lead in other sources,” said Angela Minicuci, public information officer for the Department of Community Health and Human Services. “Lead poisoning has been a problem and will always be a problem until we get all lead risks out of homes.”
Minicuci recommends that people who live in homes built before 1978 get tested for lead poisoning because of lead in pipelines and in paint.

The Centers for Disease Control and Prevention says there is no safe blood level of lead and that even low levels have been shown to have an effect, especially among children.

Lead poisoning can affect mental and physical development and at very high levels can be fatal.

Alcoa To cease smelter operation at Warrick facility

600 Employees facing termination

January 7, 2016 – by John Blair, valleywatch.net editor

Alcoa's sprawling 900 + sure facility in Warrick County, just east of Newburgh has been the largest aluminum smelter in the nation for several years as others have been forced to close due to economic issues with the price of aluminum. Now, like the others, a substantial portion of the Warrick plant will shut down in 2016. © 2016 BlairPhotoEVV

Alcoa’s sprawling 900 + sure facility in Warrick County, just east of Newburgh has been the largest aluminum smelter in the nation for several years as others have been forced to close due to economic issues with the price of aluminum. Now, like the others, a substantial portion of the Warrick plant will shut down in 2016. © 2016 BlairPhotoEVV

UnknownAlcoa, the largest primary aluminum producer in the nation announced today that it is permanently shutting down smelter operation at its Warrick facility which was the largest smelter left operating in the United States. In their announcement, they also said that about 600 employees would lose their jobs.

Alcoa has operated the smelter since 1960 and employs just under 2,000 people in total at the Warrick County facility located just east of Newburgh, IN.

Alcoa claims their decision was based strictly on market issues which have forced the price of aluminum to historic lows due to international competition.

Alcoa did say that their power plants and rolling mills will remain open and it is only the smelter part of the business that will be shuttered permanently.

Their claim that they will keep open their power plants is curious since the primary need for the electric power is smelting. If the smelters are closed, and they keep the power plants operating, it can be assumed that they will operate their power plants as so called “merchants” selling their power on the open market. But that market is not good these days as renewable energy and natural gas have caused the retirement of numerous coal fired power plants across the country,

It should be noted that the power plants operate mainly to supply energy for the smelting process and with that shutting down the demand for power will diminish considerably. Currently, the power plants that carry a nameplate capacity of 800 megawatts in total do not sell power on the open market.

However, the Warrick Unit 4 is “jointly owned with Vectren with each owning 135 MW. At this time, it is unclear how all the power will be divided although Vectren has no plans to give up their portion. If Alcoa’s part of Warrick 4 is sufficient to operate the remaining operations at the plant, then it could well be that Units 1, 2 and 3 will be permanently shuttered. This is especially so since there are a number of environmental issues those 1960’s plants must contend with, including Carbon Dioxide as it pertain to climate change. Continue reading

First-Ever National Wild Bee Map Shows Major Decline in Crucial Agricultural Regions

December 22, 2015 – by Cole Mellino in EcoWatch

Web  Bee 2-27

A team of researchers at the University of Vermont (UVM) created the first national study, which mapped wild bee populations. Their findings, which were published in the Proceedings of the National Academy of Sciences, confirm that native pollinators are in major decline in crucial agricultural regions of the U.S. They estimate that between 2008 and 2013, wild bee abundance declined in 23 percent of the contiguous U.S.

“If losses of these crucial pollinators continue, the new nationwide assessment indicates that farmers will face increasing costs—and that the problem may even destabilize the nation’s crop production,” the researchers said.

The study found that 39 percent of U.S. croplands that depend on pollinators face a “threatening mismatch between rising demand for pollination and a falling supply of wild bees.” They propose setting aside 7 million acres of land for pollinators over the next five years.

They identified 139 counties where this “mismatch” is most striking. These counties included agricultural regions of California such as the Central Valley, Pacific Northwest, upper Midwest and Great Plains, west Texas and the southern Mississippi River valley. Crops such as pumpkins, watermelons, pears, peaches, plums, apples and blueberries are most at risk because they are most dependent on pollination.

“Until this study, we didn’t have a national mapped picture about the status of wild bees and their impacts on pollination,” Koh, a researcher at UVM’s Gund Institute for Ecological Economics, said—even though each year more than $3 billion of the U.S. agricultural economy depends on the pollination services of native pollinators like wild bees.

The researchers cite “numerous threats” to wild bees, including pesticide use, climate change, disease and habitat loss.  Continue reading

Cancer studies clash over mechanisms of malignancy

December 17, 2015 – by Heidi Ledford in Nature



Most cases of cancer result from avoidable factors such as toxic chemicals and radiation, contends a study published online in Nature on 16 December (S. Wu et al. Naturehttp://dx.doi.org/10.1038/nature16166; 2015). The paper attempts to rebut an argument that arose early this year, when a report in Science concluded that differences in inherent cellular processes are the chief reason that some tissues become cancerous more frequently than others (C. Tomasetti and B. Vogelstein Science 347, 78–81; 2015).

The work led to assertions that certain forms of cancer are mainly the result of “bad luck”, and suggested that these types would be relatively resistant to prevention efforts. “There’s no question what’s at stake here,” says John Potter of the Fred Hutchinson Cancer Research Center in Seattle, Washington, who studies causes of cancer. “This informs whether or not we expend energy on prevention.”

In their Science paper, mathematician Cristian Tomasetti and cancer researcher Bert Vogelstein at Johns Hopkins University in Baltimore, Maryland, calculated the relationship between the number of stem-cell divisions and the risk of developing cancer in various tissues. Every instance of cell division comes with a risk that DNA will be incorrectly copied, leading to mutations — some of which could contribute to cancer. The duo’s analysis found a correlation: the more stem-cell divisions that occur in a given tissue over a lifetime, the more likely it is to become cancerous. Continue reading

“Winter” is colorful in late 2015

December 16, 2015 – by John Blair, valleywatch.net editor

Record breaking temperatures across the eastern half of the USA have provided more opportunities for being outdoors than normal this time of the year. But that also includes pests like those in the mosquito family and other insects. Perhaps the agreement reached last week in Paris will at least quell the advance of climate change, at least hopefully.Winter color web

Carbon capture analyst: ‘Coal should stay in the ground’

December 2, 2015 – Contact: Nicole Casal Moore at University of Michigan News. Editor’s Note: Valley Watch has opposed the use of Carbon Capture and Sequestration for mainly economic and efficiency reasons for more than a decade.

Serious flaws have been found in a decade’s worth of studies about the best way to reduce greenhouse gas emissions and stabilize the climate.

The findings, from the University of Michigan, are released as world leaders at COP21 attempt to negotiate the globe’s first internationally binding climate agreement.

The U-M researchers have found that most economic analysis of carbon capture and storage, or CCS, technology for coal-fired power plants severely underestimates the technique’s costs and overestimates its energy efficiency. CCS involves sucking carbon out of coal-fired power plants’ flue gases, compressing it and then injecting it deep underground.

The new analysis puts the cost of reducing carbon emissions with CCS-equipped coal plants higher than any previous study—and most importantly, higher than wind and comparable to solar power. It’s the first study to confront the so-called “energy loop” inherent in the CCS process.

Beyond a one-time “energy penalty” these plants pay because they have to burn more coal to power devices that capture carbon, the researchers say the disadvantage compounds until fuel costs leap to four times today’s accepted estimates.

“The conclusion is that renewables will be a cheaper alternative to reducing carbon emissions from coal, at least in the United States and likely globally,” said Steve Skerlos, U-M professor of mechanical engineering, and civil and environmental engineering.

“To us, this means policymakers need to stop wasting time hoping for technological silver bullets to sustain the status quo in the electric sector and quickly accelerate the transition from coal to renewables, or possibly, natural gas power plants with CCS.”

New study says typical Evansville air is bad enough to trigger serious heart attacks

November 16, 2015 – by Daphne Chen in the Deseret NewsEditor’s note: For those who follow such mundane things as air pollution data, it is clear that the many days in Evansville and surrounding environs, reach levels referred to in this new study. Unfortunately, government officials at every level, local, state and national dismiss poor air quality in the region as just  cost of doing business. air pollution alert

If you have heart disease, yellow may not be your friend.

Patients with heart disease have an increased risk of having a serious heart attack even during moderate air quality days, according to findings released last week by Intermountain Heart Institute.

Kent Meredith, a cardiologist with Intermountain Medical Center in Murray and one of the researchers on the study, said the risk begins when the level of fine particulate matter — what scientists call PM2.5 — reaches 25 micrograms per cubic meter of air.

That falls in the range of a yellow air quality day — what the Utah Department of Environmental Quality labels “moderate” air quality.

“Patients who have known heart disease are going to be more vulnerable on those days when you see the air pollution spike,” Meredith said. “Those are days when they probably ought to adjust their activities.”FIne particle comparison

The study involved analyzing two decades of data from more than 16,000 Intermountain Healthcare heart patients along the Wasatch Front, cross-referencing it with 20 years of local air quality data.

“It’s a very complete, very big study in terms of the number of patients, which allows us to look for even small effects,” Meredith said.

Researchers found that for every 10 micrograms per cubic meter increase in PM2.5 levels, a patient’s risk for serious heart attack rose by 15 percent.

The study suggests that people with coronary artery disease should limit their outdoor exposure on many yellow days and all orange and red days. Continue reading

Breaking News: Valley Watch, colleagues, win Vectren appeal

October 29, 2015 – by the Indiana Law Blog. Editor’s note: We would almost certainly expect that Vectren will appeal this decision for either a rehearing before the same Court of Appeals or seek review by the Indiana Supreme Court.

BIRD W: ADDRESSIn Citizens Action Coalition of Indiana, Inc., Sierra Club, Inc., and Valley Watch, Inc. v. Southern Indiana Gas and Electric Co. d/b/a Vectren Energy Delivery of Indiana, Inc., Ind. Utility Regulatory , a 34-page opinion, Judge Bradford writes:

On January 17, 2014, Appellee-Petitioner Southern Indiana Gas and Electric Company d/b/a Vectren Energy Delivery of Indiana (“Vectren”), a public utility company which provides electricity to southern Indiana residents, filed a petition with Appellee the Indiana Utility Regulatory Commission (“the Commission” or “IURC”) for approval of projects to modify their current coal-powered generating stations so as to meet new EPA standards. The petition also requested financial incentives and reimbursement from ratepayers for costs associated with the projects. Appellants-Intervenors Citizens Action Coalition of Indiana, Inc., (“CAC”) Sierra Club, Inc., and Valley Watch, Inc. (collectively “Appellants”) intervened in the action and, in addition to the Indiana Office of Utility Consumer Counselor1 (“OUCC”), opposed Vectren’s petition. Appellants argued that retiring some or all of Vectren’s current coal-powered generators and replacing them with new natural gas-powered generators was a more cost-effective plan than Vectren’s proposal to install emission controls on its current generators. Ultimately, the OUCC ceased its opposition to Vectren’s proposal prior to the Commission’s decision.The Commission found that Vectren’s proposal was reasonable and necessary, approved the proposal, and granted Vectren’s request for reimbursement of project costs. On appeal, Appellants argue that the Commission failed to make necessary findings on (1) facts material to its determination of the issues and (2) statutory factors required to be addressed prior to authorizing the use of clean coal technology. In response, Vectren claims that Appellants’ appeal is moot and that the Commission made all necessary findings. We find that the Commission erred in failing to make findings on the factors listed in Indiana Code section 8-1-8.7-3 and, accordingly, we remand with instructions. * * *

We find that (1) the Appellants’ claims are not moot, (2) the Commission did not err in failing to consider the necessity of Culley unit 2 or the reasonableness of Vectren’s delay in filing its petition, and (3) regarding the soda ash and hydrated lime injection systems, the Commission erred by failing to make findings on the statutory factors listed in Indiana Code section 8-1-8.7-3 and by failing to grant or deny Vectren’s request for a CPCN thereunder. Accordingly, we remand the case to the Commission with instructions that the Commission make the required findings under Chapter 8.7.

Modern living could endanger health, food and ecosystems

October 18, 2015 – by Judy Siegel-Itzkovich in the Jerusalem Post

Living under constant and stable temperatures throughout the year due to air conditioning, heating and artificial lighting at night is liable to harm our health, food security and ecological systems, according to a international study by 63 researchers from 24 universities, including Tel Aviv University. The study was published in the British journal, Proceedings of the Royal Society B.

Professor Noga Kronfeld- Schor, a behavioral neuroscientist who heads the zoology department of TAU ’s life sciences faculty, said that these artificial environmental conditions create an “unending summer”.

Kronfeld-Schor explained, “The pace of life on our planet is [naturally] affected by seasonal changes. Plants and animals exhibit annual cycles in physiology, health, morphology, behavior and demography.

Our survey points to the fact that humans are not any different, and that we show significant annual rhythms in demography, health and well-being.”

She added that we usually do not pay attention to these seasonal changes because they are very slow.

“We feel our internal clock when we’re in jet lag, for example, but we pay less attention to the seasonal ticking – partly because we live in an artificial environment of ‘constant summers’ with steady temperatures and available lighting. But studies on other species prove that even after many years under set and artificial conditions, animals continue to ‘obey’ their seasonal clock, and statistical analyses show that humans are no different. We express different genes and are ill according to seasons – and are even violent and go to war according to seasons in the year.”

While the artificial environment does not cancel the season clock of humans, Kronfeld-Schor said: “We still don’t know how this environment affects our biological clock. We have a growing number of studies that point to animals losing their synchronization.

For example, migratory birds leaving one country are supposed to reach their target country on an exact date when there are enough hatching caterpillars to serve as a source of food.

The caterpillars time their hatching according to temperatures in the environment, but because of global warming, they do so before the birds arrive, so the birds die of hunger.”

The new article stresses the importance of better understanding of seasonal biology, especially based on disruptions caused by climate changes, the modern way of life and additional effects.

KU, LG&E “officially” retire the antiquated Green River Station

October 8, 2015 – News Release from LG&E and KU in the Owensboro Messenger-Inquirer

It began powering customers across the Commonwealth before some areas even had electric service. Now after 65 years of providing safe, reliable energy, the turning of generating units at Louisville Gas and Electric Company and Kentucky Utilities Company’s Green River Station has ground to a halt. The company officially retired the plant’s final two units just before midnight, September 30.


The antiquated Green River Station is now officially retired. Compared to other plants, like TVA’s Paradise Plant nearby, it was a small facility but a big polluter, nevertheless. File Photo © 2015 BlairPhotoEVV

Hailed by Kentucky officials as “the greatest industrial innovation of the century,” Green River was put into service in 1950 to help meet post-World War II energy demands. Strategically located in western Kentucky, the plant played a key role in supporting the region’s dramatic economic growth by taking advantage of abundant, low-cost coal supplies in the area and serving as a critical energy hub that interconnected and supplied power to Kentucky Utilities’ entire system. At the peak of its operations, the plant’s four generating units combined to produce more than 250 megawatts of power.

“This plant might be a small one by today’s standards, but it’s also been a mighty one,” said Green River Station General Manager Tom Troost. “It’s met the challenge of increased demand and endured flooding, ice storms and more than six decades of service in an industry that is constantly evolving.” Continue reading

Duke gets “sweetheart deal” from North Carolina Governor, an ex-employee of Duke Energy

October 4, 2015- by the Editorial Board of The Charlotte News and Observer

A massive coal ash problem exists at the Duke Energy Gibson Station in SW Indiana that goes largely ignored by Indiana environmental officials. Already, the drinking water for the little community of East Mt. Carmel, IN is so contaminated with selenium and other substances that it is unsafe for human consumption. Indiana seems to simply look the other way at this and the other numerous power plant ash issues across the state. © 2010 BlairPhotoEVV.

A massive coal ash problem (Foreground) exists at the Duke Energy Gibson Station in SW Indiana that goes largely ignored by Indiana environmental officials. Already, the drinking water for the little community of East Mt. Carmel, IN is so contaminated with selenium and other substances that it is unsafe for human consumption. Indiana seems to simply look the other way at this and the other numerous power plant ash and waste issues across the state. © 2010 BlairPhotoEVV.

Well, one has to admire the legal tactics if not the outcome. Duke Energy, after years of coal ash violations, made a deal with the state last week to make a $7 million payment, $500,000 for each of 14 coal ash pit and pond sites to settle the matter. In February, fears of a breach became a reality when a Duke coal ash pit in Western North Carolina spewed 39,000 tons of toxic waste into the Dan River. 

Criminal investigations ensued. Gov. Pat McCrory, a former long-time Duke employee when he was mayor of Charlotte, the company’s headquarters, vowed a righteous response. 

Indeed, state environmental regulators levied a $25.1 million fine against Duke. But that all went away Tuesday when the state and the company settled for that $7 million. Duke called it a payment and didn’t even seem to concede it was a fine. Dupe-Energy-Logo-trans

Frank Holleman, a lawyer for the Southern Environmental Law Center, rightly called it a sweetheart deal for Duke. “There’s a $7 million fine,” Holleman said, “but Duke gets amnesty at every single site in the state. Where is any new requirement on Duke to do something it wasn’t already required to do?” 

Duke is paying millions for cleanup and wrestling with what to do about remaining coal ash pits, which contain heavy metals that are an environmental hazard. Duke says tainted groundwater near the sites contains “trace elements” of the metals.

The state in this case appears to have fallen victim either to a botched investigation or to the high-dollar legal team Duke threw at the problem. 

In legal filings, the company claimed that Donald van der Vaart, secretary of the newly renamed state Department of Environmental Quality, told his staff to figure a big fine for Duke so that McCrory wouldn’t look bad as a former Duke employee. For its part, DEQ said Duke had been delaying action for years. 

But there seems little doubt that the country’s largest electric utility certainly bested the state in this case. Going from $25 million to $7 million doesn’t seem the shrewdest negotiating on the state’s part. And the coal ash problem is an ongoing threat.

A spokesperson for DEQ tried, unsuccessfully, to put a good face on the situation: “We both see value in putting this case behind us so that we can turn our full attention to the coal ash cleanup and basin closure process.” It’s likely some of Duke’s “full attention” was directed toward a victory party somewhere in Charlotte.

This tepid response to reprehensible threats of environmental problems related to coal ash only underscores the attitude of the governor and GOP legislative leaders that business should be left alone with regards to regulation, and if something happens to the environment, well, that’s just the chance you have to take.

Breaking News: Duke rate hike from Edwardsport plant remanded

Dupe-Energy-Logo-dirtySeptember 23, 2015 – by Dave Stafford in the Indiana Lawyer. Editor’s Note: Valley Watch has been fighting this plant since its inception in 2004. In fact, we were instrumental. along with now deceased, Al Harding, in persuading Vectren to drop their proposed 20% investment in this fiasco. Finally after all these years our dedicated efforts are paying off for Duke ratepayers, at least some.

The Indiana Utility Regulatory Commission must weigh for the third time rate increases for Duke Energy consumers connected to delays in opening the Edwardsport coal gasification plant in Knox County.

The Indiana Court of Appeals sent the matter back to the IURC in a suit brought by intervening interest groups, Citizens Action Coalition of Indiana, Inc., Save the Valley, Inc., Sierra Club, Inc., and Valley Watch, Inc. v. Duke Energy Indiana, Inc., Indiana Utility Regulatory Commission, 93A02-1503-EX-184. The appeals court held the commission erred by not reopening the record after a prior remand and relied on evidence not in the record in determining the reasonableness of rate increases. The panel affirmed IURC rulings that a three-month delay in the plant’s commissioning was not caused by unreasonable actions by Duke, and therefore the cost could be calculated to ratepayers. The panel also affirmed the commission’s determination that the plant was partially in service for federal tax purposes before the in-service operational date in the settlement agreement.

“Based on our review of the record, there was ample evidence regarding the three-month delay and its impact upon Duke’s petition for cost recovery, and there was no need for additional evidence on remand to address that issue,” wrote Senior Judge Betty Barteau. “By contrast, there are insufficient findings as to the value of the rate increases caused by Duke’s declaration that the plant was partially in-service for tax purposes, and whether the increases were reasonable.

“Furthermore, the Intervenors did not have an opportunity to seek discovery on the rate increases, due to Duke’s late clarification of the issue. In addition, the Commission on remand considered additional evidence in the form of orders from ECR 19 and ECR 20, although those orders were not part of the record in IGCC-9 and the Commission did not follow the procedure for taking administrative notice of prior orders. The Commission’s consideration of these orders sharply contradicts its determination that it did not need to reopen the record on remand to receive additional evidence,” Barteau wrote.

“Under these circumstances, on remand the Commission should reopen the record, receive additional evidence … and issue findings of fact on these issues:  (1) quantifying the impact upon Duke’s proposed rate increases in this case resulting from Duke’s declaration that the plant was partially in-service for tax purposes; and (2) determining whether the proposed increases were reasonable per Indiana Code section 8-1-8.8-12(d).”

Algae bloom grows, not impacting lower Ohio River, yet. Advisory area stretches from W. Va. Line to Cannelton Locks and Dam.

September 23, 2015 – by the Kentucky Division of Water. Editor’s note: Valley Watch contacted Orsanco’s Environmental Specialist, Greg Youngstrom 9/23 to discuss the situation as it currently stands. We found that the farthest downriver the algae has bloomed is about thirty miles downriver from Louisville, approaching Leavenworth, IN. We will try to monitor the situation as and if it moves further downstream.

The Kentucky Division of Water (KDOW) and the Kentucky Department for Public Health (KDPH) are re-issuing a harmful algal bloom (HAB) recreational advisory for the Ohio River and tributaries, extending the advisory downstream from the West Virginia state line to the Cannelton Locks and Dam located at Cannelton, in Hancock County, Kentucky.

KDOW and Ohio River Valley Sanitation Commission (ORSANCO) personnel observed favorable water conditions for HAB development and made visual confirmation of HABs in the McAlpine pool at Louisville, Carrollton and Madison, Indiana. In addition, KDOW staff observed HABs in the Cannelton pool at West Point. Preliminary analysis indicates that microcystin toxins are occurring in these pools above advisory thresholds, which warrants the advisory to be extended downstream.

Water swallowed during recreational activities in this body of water may increase the risk of gastrointestinal symptoms such as stomach pain, nausea, vomiting and diarrhea. Skin, eye and throat irritation and/or breathing difficulties may also occur after contact.

On Aug. 31, KDOW received a report of an algal bloom on the Ohio River near Greenup. Subsequent sampling of the river indicated higher levels of microcystin toxins existed in some areas of the Ohio River from Ashland to the Meldahl Dam. KDOW issued a recreational advisory on Sept. 4 from the West Virginia line to Meldahl Dam. Since that time, conditions favorable for the development of HABs have persisted throughout the river basin, and additional HABs have formed further downstream.

On Sept. 11 the advisory was extended to the Markland Dam when data from the Markland pool indicated HABs were occurring throughout the pool. Observations of a significant bloom near Carrollton and Madison were made by ORSANCO staff on Sept. 16. On Sept. 17, KDOW staff observed blooms at Cox Park and Harrods Creek in Louisville and at Prospect. KDOW personnel also observed a significant bloom near West Point on Sept. 17. These observations and preliminary analysis indicate the need to extend the Ohio River and tributaries recreational advisory beyond the Markland Dam to the Cannelton Dam. This advisory includes the McAlpine pool which includes the area near Louisville. Samples have been collected and are being analyzed to confirm the presence of microcystin toxins.

This is a recreation advisory only.

There have been no detected microcystin toxins reported in the finished, treated water from public water systems which draw from the river. Precautions are being taken to monitor river water at public water supply intakes. The drinking water plants which draw from the river are optimizing their treatment to address the bacteria in the raw water, including using activated carbon and other treatment methods. KDOW will continue to sample and monitor the public water systems’ raw water and finished, treated water during the harmful algal bloom.

Harmful algal blooms arise when there are excess nutrients (phosphorus and nitrogen), sunny conditions, warm temperatures and low-flow or low-water conditions. KDOW anticipates that these conditions will persist in the Ohio River until flow in the river increases significantly and water temperatures decrease. At present, forecasts do not indicate significant changes in temperature and precipitation patterns over the next several weeks.

Blue-green algae occur naturally in the environment and are a vital part of the ecosystem. The more typical green algae, which do not produce toxins, come in many forms and may appear as underwater moss or stringy mats. Blue-green algae, on the other hand, appear as slicks of opaque, bright-green paint, but closer inspection often reveals the grainy, sawdust-like appearance of individual colonies or bacteria.

The color of the algae may also appear red or brown.

The following guidelines are recommended to avoid exposure to HABs:

  •   Individuals should avoid direct contact with affected water that has unusual color or where blue-green bacteria have been identified, including swimming, wading, paddling, diving and water skiing.
  •   People who are prone to respiratory allergies or asthma should avoid areas with HABs. Children may be particularly sensitive.
  •   If contact has been made with water containing blue-green algae, wash off with fresh water. In some cases, skin irritation will appear after prolonged exposure. If symptoms persist, consult your health care provider.
  •   If fishing in affected waters, fish fillets (not organs) may be consumed after the fillets have been rinsed in clean, non-lake water.
  •   Prevent pets and livestock from coming into contact with water where HAB is apparent. If you are concerned that you have symptoms that are a result of exposure to HABs please see your doctor and call your local health department.For additional information about this advisory, contact Andrea Keatley at the Kentucky Division of Water at (502) 564-3410 or Justin T. Carey, Division of Public Health Protection and Safety, Department for Public Health, at (502) 564-7398. http://water.ky.gov/waterquality/pages/HABS.aspx
